BT Margin Lending 35% but watch the 75% max for one stock rule. My HDR has risen so that I breached it last week and they dropped HDR from 35% to 0% and requested I either sell them or pay a huge margin call. Instead I sold a small amount so as to drop just below the threshold which gave a large amount available for trading and then transfered 1/3 of my HDR holding out to a non-margin broking account.
